Add versions

Update

Closing this in favor of an epic gitlab-com&8 (closed)

This will be necessary for replacing the Help section of the Rails app (https://gitlab.com/gitlab-org/gitlab-ce/issues/18739).

Decisions:

Create onbuild Docker images
Create branches in the docs site that match each release
Create separate Dockerfiles for each branch with the versions it should pull from
Create an archive Docker image every month containing all previous versions https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/199
Create an archives page with links to the archives and Docker images https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/199
Make sure CE is not included in the menu for stable and master branches (the compile_prod job makes sure of this)
Use a backup registry, prob on dev (enable mirror pushing) #179 (closed)
Use custom Docker image when rolled to production https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/232
Create a detailed readme for all the tooling

The "Edit on GitLab.com" filter will need to be updated (use only on the master branches)
Handle robots.txt to exclude the versioned pages
Handle the sitemap.xml for each version

Create a dropdown with the versions gitlab-com/gitlab-docs#180
Have a banner at the top if you're not on the latest version and a dropdown to choose the version https://gitlab.com/gitlab-com/gitlab-docs/issues/181

Edit Algolia's config to include search results for versions https://gitlab.com/gitlab-com/gitlab-docs/issues/182

You'll need Docker installed, then run:

docker run -it --rm -p 4000:4000 registry.gitlab.com/gitlab-com/gitlab-docs:latest
